Understanding Phantom Particle Counts
Filtertechnik have developed a portfolio of products for accurate real-time monitoring of Particulate, Water Content and Remaining Life for Oil and diesel fuels. We offer 2 particle counting approaches, new Digital Imaging technology and more traditional Laser Particle counters.
S120 Digital Imaging Particle Counter
The S120 Digital Imaging Particle Counter is a huge step forwards in accurate determination of oil and diesel fuel Particle counting using revolutionary new digital imaging and advanced algorithyms to analyse particles on the fly. A wider particulate size categorisation (4, 6, 14, 21, 38, 70 and >100 microns are counted and categorised) as well as shape recognition sorting particles 20 microns and above into; Sliding, Cutting and Fatigue Wear. An additional major feature is bubble recognition and elimination from ISO counts.
Filtertechnik have conducted extensive testing of both Digital Imaging and
Laser counting when Siloxane based anti-foaming additives are present in
mineral oil, especially polydimethylsiloxane, a common additive to hydraulic
oils. This additive causes phantom
particle counts with laser counters but not
with digital imaging. For more information on this phenomenon please

DIGITAL IMAGING PARTICLE COUNTERS
Particle
Pal Pro

S120
Digital Imaging Particle Counter
|
The revolutionary new Digital Imaging particle counting technique gives unprecedented insight into the type and quantity of contamination in any given oil or diesel fuel sample. ISO/NAS/SAE counts as well as a broader micron range, shape recognition, bubble elimination and the ability to handle higher viscosities.
This breakthrough technology uses advanced algorithms to calculate the size and shape of particulate on images taken at between 2 & 4 frames/second. The technology also gives root cause shape recognition to the particulate in live systems or bottle samples of any oil. Special algorithms and AI analyse images on the fly with a resolution of 2 microns up to several hundred microns. High-resolution images are saved for further analysis and reporting such as the one above.
Particles are counted and categorised into Fatigue, Sliding or Cutting Wear. Air Bubbles and Water Droplets are counted and then eliminated from the counts making this suitable for live testing or permanent installation on systems where air is present such as large gearboxes. In addition, anti-foaming additives such as polydimethylsiloxane are not counted as particles by digital imaging, this is a major advantage over Laser Particle counters which see's the micelle-like formations created by this additive as contamination, these are phantom particles, often resulting in particle counts being raised by 2 to 3 ISO codes, especially the 4 and 6 micron channels.
Filtertechnik supply the S120 counter as a stand-alone particle counter for integration into live systems for 24/7 monitoring. Alternatively, we have developed a range of portable oil analysis cases designed to give on the spot oil analysis and a deep understanding of the type and quantity of contamination in any given oil sample. Built-in software takes readings from the new digital imaging technology and presents Engineers with an easy to understand analysis including images of contamination in the oil sample.
MOISTURE SENSORS
Filtertechnik
offer two types of water sensors for determining the quantity of water in oils,
fuels and biofuels; our RH sensors and our WMS500 PPM sensors RH
Water Monitor: Our RH (Relative Humidity) water monitor gives the percent
saturation of a given fluid. 100% saturation is the point at which suspended
water becomes harmful free water. These sensors are lower cost and are very
useful for hydraulic applications. Outputs are scaled and 4-20mA. WMS500
PPM Sensor: Our Genuine PPM sensors are highly
accurate parts per million (PPM) sensors and are particularly useful for transformer
oils and diesel fuels or biofuel. The sensors are calibrated to a Karl
Fischer device and fully temperature compensated. To
understand the different relationships between %RH and PPM please see below: Parts
per million (ppm)
: Our
PPM sensor gives a count of the absorbed water up to the saturation point of a
given oil or fuel. Beyond the saturation point the sensor 'locks out' as free
water will have formed. Relative
humidity:
Relative
Humidity or RH is expressed as a percentage. 100% RH equates to the maximum
amount a given oil or fuel can hold (absorbed water) before it becomes
saturated and free water forms. To

increased use of siloxane based anti-foaming agents is causing issues with
laser counter technology. IMAGINE
THIS: You have been filtering 150 litres of hydraulic fluid off-line with
staged 5 and 1 micron filter elements at a rate of 25 litres per minute (1,500
litres per hour). You have been using a laser light-blockage method (LBM),
automatic particle counter to verify the fluid cleanliness. The starting
cleanliness per ISO 4406:2017 was 25/22/15. After eight hours, the cleanliness
has only dropped to 22/20/13. You've checked that the filter element is not
clogged and not in bypass. You even went through the trouble of making sure
there was an element actually in the filter. How is this possible? What you're
likely experiencing is a classic case of "phantom" particle counting. Phantom
particle counting is a documented problem, encountered when using laser-based
LBM particle counters to verify the cleanliness of mineral based fluids
containing certain insoluble additives. Silicone-based antifoam agents such as
polydimethylsiloxane are common additives causing problems. Fluids used in
mobile fluid power systems are typically formulated to contain high antifoam
concentrations. Research has suggested that through differential surface
tension, the silicone-based antifoam additive agents adhere to the inner wall
of microscopic, entrained air bubbles, resulting in micelle-like encapsulations
of the additive agents that then take on the apparent shape characteristics of
a water droplet. The micelle-like antifoam agent encapsulations typically range
in 4-10µm in size. Once the encapsulations rise to the fluid surface, the
agents quickly pierce the air bubble and return back into the fluid. In a
related study on the effects of a variety of nonsolid contaminants and
additives on LBM particle-counting accuracy, it was found that a base stock
mixture containing 0.02% (by weight) of a silicone antifoam agent increased the
particle count by a minimum factor of three. The erroneous particle accounts
were particularly evident in the 4µm and 6µm channels of the ISO 4406
cleanliness standard. Light
blocking method (LBM) Laser particle counters are useful in many applications
and the principle of the method is fundamentally simple. Fluid flows through a
measurement cell containing a light source on one side and a receiver
(photodetector) on the opposite side. The light source becomes partially
blocked as particles pass through the measurement cell, creating a light
radiation differential (a shadow) – corresponding to the circular
cross-sectional size of the passing particles. Because of this fundamental
operating principle, LBM particle counters suffer from a key drawback: the
inability to discern solid contaminants from other contaminants such as water,
air bubbles, phantom particles, and so on. So, how can the phantom particles be
overcome using automatic particle-counting technology? There is an alternative
solution. Digital imaging particle counting uses
size and shape-recognition technology, based on advanced algorithms to
distinguish contaminants. For example, a direct imaging particle counter can
distinguish contaminants into fatigue, cutting and sliding wear, as well as
fibre and air bubble categories based on shape characteristics. It can also
recognize water droplets (though water droplets are typically not recorded).
The distinction of contaminants allows for more accurate particle counting, by
negating nonsolid particles like entrained air bubbles and water droplets. The S120 digital imaging particle counter can
recognise solid particles and summarize them into 4, 6, 14, 21, 38, 70 and
>100 micron ranges. It can also recognise shapes and give individual shape
recognition counts as sliding, cutting and fatigue wear particles. Bubbles are
also recognised and removed from the counts. Therefore,
digital imaging particle counting technology can negate the micelle-like
antifoaming additive encapsulations as water droplets – phantom particles –
allowing users to understand the condition of their fluids with confidence.
Various real-world case studies demonstrate how the Particle Pal Pro a fluid
condition monitoring solution with digital imaging particle counting
technology, can overcome phantom particle counting. In
a lab-based test conducted on base oil with no additives, Filtertechnik ran 2
particle counters feeding from the same oil warmed to 40°C. A PC9001 laser
counter and an S120 digital imaging particle counter. Filtertechnik then dosed
in exactly 100ppm polydimethylsiloxane anti foaming additive. The results were
immediately apparent in the laser counter, affecting the 4 and 6 micron counts
by up to 3 ISO codes, the 14 micron count slightly less so, but still an
increase of 1 ISO code. The digital imaging counter remained unaffected by the
additive. An
OEM of large off-highway equipment was experiencing continuous particle counter
inaccuracies at a verification stage of assembly. The rejections due to fluid condition
were mounting, causing delayed shipments and significant related costs. The
average holding time delay due to rejection was seven days, which incurred a
holding cost of £1,000-a-day per unit. At the consultation phase of the case
study, eight units had been delayed. The
diagnosis was in: the existing laser light-blockage-type particle counters were
providing inconsistently high and erroneous particle counts. The ISO 4406
cleanliness would frequently measure 23/22/19, despite a strong fluid-maintenance
and conditioning regime. Third-party fluid analysis reports and fluid
datasheets suggested that the synthetic hydraulic fluid contained a high
concentration of a siloxane (silicone derivative) antifoaming additive, known
to cause phantom particle measurements in LBM automatic particle counters. Filtertechnik
provided an extensive on-site demonstration that proved the advanced digital
imaging technology of the Particle
Pal Pro portable fluid contamination monitoring solution, which
measured an average ISO fluid cleanliness of 15/14/10. This allowed the
customer to successfully process the fluid and pass six units during the first
day of demonstration. The two remaining backlogged units passed early on the
second day of demonstration. The savings evidenced by the demonstration equated
to approximately 35% in cost savings and an 81% reduction in holding time. For
